16 mm. Sound Film Dimensions

Russell P. May

A method is set forth for the derivation of dimensions and locations of the final projection print and all camera, printer, and recording apertures, consideration being made for film weave, shrinkage, and mechanical tolerances in the apparatus involved in producing and projecting the film. — Two methods of producing films are considered: (a) Projection positive print made from a 16 mm. dupe negative by continuous contact printing, where the dupe negative is made by optical reduction of the 35 mm. picture from a master positive and the sound re-recorded from a 35 mm. sound track, and (b) production of the projection positive print from a 35 mm. picture negative by optical reduction and re-recording of the sound from the 35 mm. sound film directly to the final 16 mm. positive. The method provides for modification of these processes so that any combination can be used.
